Feasibility Study
Project objectives
Protection of the western mountain aquifer and safeguarding the environment
in Baqa Al-Sharqia and Nazlat through safe collection and treatment of
wastewater.
Project description
Infiltration of wastewater through cesspits that discharge into wadis formed
the main source of groundwater pollution in the project area. Therefore, this
project aimed at protecting the mountain aquifer in Baqa Al-Sharqia and
controlling wastewater pollution in Wadi Abu Nar. The United Nations Development Programme / Programme for Assistance to the Palestinian People supported the identification of the best solution for treatment of the waste-water
of the municipality and preparation of a detailed design for the construc-tion of
wastewater network in the remaining unserved areas in Baqa Al-Sharqia (about
40 %) and Nazlat area (100%). The new network served about 5,000 people.
Project data
Assessed investment needs of 8.84 Mio US$ and site supervision needs of 0.26
Mio US$ (1st stage)
Project specifics
The project was implemented during and immediately after the 2014 Israel–
Gaza conflict.

The feasibilty study developed several different options and compared them on
technical, operation, financial, socio-economical and environmental levels
(multi-criteria matrix). The best option resulted in 25 km of primary and
secondary network; four pumping stations (2 kW; 3 kW; 10 kW and 21 kW
respectively) and a treatment plant of wetland type (1,500 m³/d; 15,000 PE).
On the short run, in order to minimise environmental threats, the connection
to the existing Israeli WWTP in Baqa Al Gharbiya was suggested. Wastewater
reuse was achieved by storage and irrigation of trees along the wadi until the
farmers will connect their fields to the irrigation system. For the primary and
secondary network and the smallest pumping station a detailed design was
carried out as well as tender documents elaborated. The feasibility study was
developed in parallel to the Master Plan for rehabilitation of Wadi Abu Nar.
